The uncertainity in position of an electron is equal to its de-brogl

1.	The uncertainity in position of an electron is equal to its de-broglie wave length. Theminimum percentage error in itsmeasurement of velocity under thiscircumstance will be approximately(A) 4(B) 8(C) 22(D) 18
Answer» ong>Answer: HI friend Hope this answer helps you The answer is 8 Explanation: ACCORDING to question, uncertainty in position is equal to De broglie wavelength, therefore dx= mv h Now, according to uncertainity principle, dx.dp= 4π h as minimum is required. So, mdv.dx= 4π h . By putting the value of dx from above, we GET v dv = 4π 1 . So % ERROR = v dv ×100= 4π 100 =8

HI friend

Hope this answer helps you

The answer is 8

Explanation:

ACCORDING to question, uncertainty in position is equal to De broglie wavelength,

therefore dx=

Now, according to uncertainity principle, dx.dp=

4π

as minimum is required.

So, mdv.dx=

4π

By putting the value of dx from above, we GET

4π

So % ERROR =

×100=

4π

100
